ABSTRACT:
A method for determining the presence of multiple carrier frequency components in an electrical signal by calculating a value for at least one characteristic of the set of peaks in a defined portion of the frequency spectrum, such as the number of peaks within a defined portion of the frequency spectrum or the average spacing between pairs of peaks, and defining a range of values of the characteristic that would indicate the presence of multiple carrier components, and comparing this calculated characteristic value against the values in the defined range of values.
